Volvo 2.0T
Five-cylinder turbocharged petrol engine with 180 hp. Solid engine from the modular range, sharing many parts with the 2.4/2.5L variants. Service the PCV system and timing belt regularly.
Comfortable turbo cruiser
With the automatic the 2.0T loses some sportiness but remains a pleasant long-distance companion.
Engine Weaknesses 4
Interference engine — timing belt failure means total engine damage. Check CVVT unit during belt change; seals age and oil can enter the timing belt area, destroying the belt prematurely.
Symptoms: No warning before belt breaks. CVVT fault: rattling noise on cold start, rough idle.
The PCV hose from the engine block to the separator box develops cracks on the underside that are invisible from above. Result: oil accumulates on top of the engine and in the spark plug wells.
Symptoms: Oil accumulation on top of engine, oil in spark plug tubes, whistling noise under load, slight oil consumption.
The electronic throttle module (ETM) wears out through internal contact corrosion and loose connectors. Mainly affects vehicles up to 2002. Volvo extended the warranty to 10 years. Rebuilt units available.
Symptoms: Check engine light, reduced power, limp mode, engine stalls at idle, fluctuating idle speed.
The turbocharger boost control valve can fail over time. Affects all turbo variants of the modular family (2.0T, 2.4T, 2.5T). Announces itself with a noticeable loss of power.
Symptoms: Noticeable power drop, turbo fails to build full boost, check engine light.
Vehicle Weaknesses 10
The 5-cylinder diesel is prone to cylinder head cracks and worn cylinder liners, particularly at higher mileages. Check the coolant level regularly.
The automatic transmission in the S80 I is considered failure-prone and costly to replace. Repair at a specialist costs €3,000–4,000; Volvo dealers charge up to €6,000–8,000. Regular fluid changes delay failure.
The Geartronic automatic gearbox in the S80 I requires a fluid change every 50,000–60,000 km. Volvo declared it maintenance-free — which has led to premature failure in many examples.
On the S80 I, tie rod ends, ball joints and control arm rubber bushings at the front axle wear above average with increasing mileage. MOT inspectors regularly flag these components.
The electric seat adjustment can jam on the S80 I and drive the seat rail to an extreme position. According to user reports, one driver was thrust against the steering wheel and could not move the seat back. Replace the control unit.
The S80 I also suffers from the P2-typical problem of leaking steering racks. The rack loses power steering fluid through aged seals. Reconditioning at a specialist saves significantly compared to a new unit.
Cold solder joints in the audio system control unit cause intermittent or complete failure. A full unit replacement costs from €500; second-hand units from breakers are a cheaper alternative.
The rubber anti-roll bar bushings on the S80 I wear prematurely — reportedly possible from as low as 10,000 km, typical from 80,000 km. MOT inspectors flag anti-roll bar play above average frequency on the S80.
From around 50,000 km S80 I owners report increasing squeaks and rattles inside the cabin. Door trims, wiring looms and plastic parts loosen and produce annoying noises on poor road surfaces.
Window regulators automatically pull the glass back up after about 75% of closing travel, because hardened door seals trigger the anti-trap protection. Silicone spray on seals or seal replacement resolves the issue.
